A woman who is accused of stabbing a man in his neck as he slept has been forced to remove her niqab in the Victorian Supreme Court.

Momena Shoma, 25, has pleaded guilty to a single count of engaging in a terrorist act after the ISIS-inspired attack on Mill Park father, Roger Singaravelu, in February.

The Bangladeshi student allegedly stabbed Mr Singaravelu with a 25cm knife as he slept near his young daughter.

She later told police she came to Australia for the sole purpose of carrying out a terrorist attack on behalf of Islamic State.

Shoma refused to stand as Justice Elizabeth Hollingworth entered the court but complied with a request to remove her niqab to prove her identity, leaving it off for several minutes while entering her formal plea of guilty.
